Ender's Game star Asa Butterfield has signed on to star in the sci-fi adventure Out of This World for Relativity Media. Relativity Studios is behind the project, which has Peter Chelsom (Hector and the Search for Happiness) set to direct. The story begins with a billionaire entrepreneur's mission to colonize Mars, which results in a female astronaut becoming pregnant on the planet.

The astronaut died during childbirth, but her infant son was raised in secrecy on Mars. 16 years later, after returning to Earth, the teenage boy (Asa Butterfield) enlists the help of a mission specialist and connects with a young woman he has been communicating with. They both set off on a road trip across America to find the father he never knew.
